CYCLOMETER.

:PEGIFICATION forming part of Letters Patent No. 508,405, dated November 14, 1893.

Application filed May 6 1893- To all whom it may concern.-

Be it known that 1, CHARLES H. CLAWsoN,

prising registering disks, the first or unit disk being intermittently rotated by the intermit-c tent engagement of a stud upon a rotating arbor, shaft or post, which engages with said disk to rotate it one space with each full rotation of the arbor; a tens disk with which the unit disk engages to rotate it one space, with each full rotation of the unit disk; a drive ratchet upon said arbor, shaft or post and a reciprocating slide provided with a pawlin engagement with said ratchet the distance of one tooth for each and every time said slide is reciprocated.

My invention consists in the several novel features of construction and operation hereinafter described and which are specifically set forth in the claim hereunto annexed. It is constructed as follows, reference being had to the accompanying drawings, in which Figure 1, is a perspective of the cylclometer combined with a clock movement. Fig. 2, is a vertical transverse section of the same. Fig. 3, is a top plan of the same. Fig. 4c, is a top plan of the registering disks, their retaining pawls, and the driving shaft, arbor or post which intermittently engages with the unit disk or dial to rotate it. Fig. 5, is a top plan of the driving mechanism comprising the reciprocating slide, the driving pawl carried thereby, and the driving ratchet wheel and pinion, as also the pawl mechanism for preventing backward rotation of the ratchet, all in their normal position. Fig. 6, is a like View of the same showing the slide drawn out, and the ratchet rotated one tooth. Fig. 7, is a front elevation of the cyclometer, with the case and main or recording dial removed. Fig. 8, is a vertical sectional detail of hour hand post and hand, and its driving pinion, the sleeve on said post, the pointer on the sleeve, and the gear upon said sleeve, by the rotation of which-the pointer is operated.

A, is a clock movement of any desired construction, of which a is the hour-hand post, which, however, is here shown as geared to seconds, in any ordinary manner; and

b is an ordinary inclosing case, while b' is a clamp by means of which the cyclometer is detachably mounted upon aframe bar of a bicycle.

A diaphragm c separates the clock movement from the cyclometer mechanism, being centrally perforated for the post -a .to pass through it, and having a tubularstandard c through which said post passes, and -c" is the hand mounted on said post above the recording dial -c"'. Upon this standard, a sleeve d is loosely mounted, said sleeve constitntingthe hub of the gear d, and d" is the distance hand secured upon said sleeve above the recording dial. The gear d is in engagement with the drive pinion -e secured upon the driving ratchet esecured upon the shaft e".

A reciprocating slide -h is mounted by the slot and pin connections h'- upon the diaphragm, and is recessed in its inner end to straddle the post and sleeve, or standard aforesaid, and is also slotted at -7 to fit over a stud k erected upon said diaphragm, and is also provided with an abutment m against which one end of the spring mbears, its other end bearing against said stud, so that when the slideis drawn out, asshown in Fig. 6, the spring will retract it to the position shown in Fig. 5. Upon this slide a pawl n is pivoted, in engagement with the drive-ratchet e', and n' is a spring engaging said pawl to maintain it in engagement, so that when said slide is drawn out, the ratchet will be rotated the distance of one tooth, and then when the spring throws it back, the pawl will be also retracted and snap into engagement with another tooth. 7 V

The recording d ial,as shown, combines both time and distance sub-divisions, the short marks in the outer indicating seconds; the marks of the next size indicating five seconds; the next set in length indicating ten seconds, and the heavy marks extending to LIL the inner circle, indicating minutes, while the arrow-headed lines indicate thirty (30) seconds. Within the inner circle, the round dots in conjunction with the wedging or triangular marks, each indicate two hundred and twenty (220) yards, while the wedging marks each indicate four hundred and forty L40) yards or one-fourth (1:) of a mile. Each rotating movement of the, ratchet moves the hand d" a fixed distance, and the successive movements thus record the distance traveled.

The rod p in Fig. 2, is connected to the mechanism for reciprocating the sliding bar, and as that mechanism forms the subject matter of another application for Letters Patent, it is not here shown nor described, that application being filed concurrent therewith, Viz., Serial No. 472,189, filed May (5,1893.

Upon the sleeve d, an arm -r is secured, in such manner as to intermittently engage with each full revolution of the hand cZ, which makes one mile of travel with a rotating unit dial r, here shown as provided with ten pins r with which said arm successively engages, and rotates the dial one space or one unit with each engagement. This unit dial is also provided with 'an arm s, which, by each revolution of the dial, is brought into engagement with the ratchet pins sof the tens wheel -s, to intermittently rotate it one space, each space thus indicating ten miles, and thus Fig. 3, shows that fourteen miles and one-fourth have been traveled. It will also be seen that when ninety-nine miles have been traveled, both dials will exhibit the figure 9, and when one hundred miles have been traveled, both will show a naught; and the next full rotation of the hand will indicate one upon the units dial. Spring pawls -t, of any suitable construction, prevent the backward rotation of each of said dials.

To prevent the backward rotation of the driving ratchet a check pawl mechanism is shown, in which the pawl w' is pivoted upon a pin, erected upon a plate '10 secured upon said diaphragm, the pawl w being held in engagement by aspring w-; but any other kind of spring pawl, or detent, suitable for the purpose may be used.

This cyclometer can be applied to any bicycle, however geared, as when it is geared at 56, a ratchet is used having a fixed number of teeth, and when it is geared at 60, a ratchet with more teeth should be used, and so on; the radius of the gear remaining unchanged.

As at present constructed, the cyciometer is adjusted to a cycle having a drive wheel thirty inches in diameter, and no matter how high or how low it is geared, each movement of the hand, or in other words each tooth of the ratchet, indicate twenty feet of travel of the drive wheel, and this relation remains true, no matter how many teeth there are upon the ratchet wheel.

WVhat I claim as my invention, and desire to secure by Letters Patent, is-- The combination with a clock movement, and the hour-hand postand pointer thereon, of a cyclometer comprising a sleeve on said post, a hand upon said sleeve, a driving ratchet wheel, a longitudinally and intermittently operated slide provided with a pawl engaging with said ratchet, a train of gearing intermittently actuated by said ratchet to intermittently rotate said sleeve and hand, and adding dials intermittently rotated by said sleeve.

In witness whereof I have hereunto set my hand this 19th day of April, 1893.
